Abstract

A method for use in a telecommunications system in which a call sequencing facility allows a caller who is trying to reach a called subscriber to be routed to each of a sequence of telephone numbers specified by the subscriber, even though a call placed to one such telephone number is answered.

Description

Telecommunications system sequence calling
The present invention relates to the processing of call in the telecommunication system.
Just implementing or one of achieve an equilibrium ikn planning these 10 years and various farsighted notions of longer time are the ideas of sequence call.In case this characteristic is used, the telephone service user can indicate the order of telephone number to telecommunication infrastructure, can be sent out till this user " is found " to this user's calling.For example, to " 700 " telephone number, as from AT﹠amp; The user of so-called individual's " reaching easily " 700 numbers that T obtains, can indicate the number that the calling of getting to this number for example should at first send to this user's Work Telephone, if does not reply the there then, then send to the number of the cellular phone relevant with user's automobile telephone, if and does not reply the there, then send to user's home number.The prior art of this respect is representative with the technology of narration in the United States Patent (USP) 5222125 of authorizing people such as C.W.Creswell on June 22nd, 1993.
The present invention has stated in claim 1.
At accompanying drawing 1:
Fig. 1 is the block diagram of a communication network, and this network comprises a professional adjunct circuit (service adjunct) of implementing the personal telephone number business.
Fig. 2 represents to comprise the many record fields of user to this professional distributed intelligence;
Fig. 3-8 represents this program with the flow chart form, and this program is implemented principle of the present invention in professional adjunct circuit shown in Figure 1 and operator service Operator Position System (OSPS).
Fig. 9 is the block diagram of professional adjunct circuit; With
Figure 10 is the roughly block diagram of OSPS.
Fig. 1 represents a public switch telephone network 100, and it provides long-distance telecommunications service to its user as the user relevant with telephone set S1 to S4.Network 100 there is shown wherein three: 110,115 and 120 particularly including a plurality of long-distance exchanges (TS) office or switch.Network 100 also comprises a plurality of operator's position switching system offices (OSPS), there is shown one of them: 105.These switches and OSPS office interconnect through long-distance network 111.Switch and OSPS office also can be connected to one or several local telephone network central office (CO), as CO5, and 10 and 15, Service Phone machine S1 and S4 respectively, wherein telephone set S3 represents a mobile phone.
Professional additional telephone 150 is included in the network 100, according to distributing with this subscriber-related telecommunication service, handles the calling of making the personal telephone number service-user.As being described in detail below, the information that is included in this distribution can be through being imported by this user with the reciprocation of voice interaction action system and/or changing.
The telephone subscriber who calls out from telephone set S1 can be by dialling predetermined phone numbers reservation personal telephone number business, network 100 be established to the connection of the terminal 160 of being kept an eye on by the business agent.Represent interactive result with this, new user is assigned with a unique personal call service number.In illustrative embodiment, add service code " 700 " before the personal telephone number.
Relevant with personal telephone number is people's identification code (PIN) and four caller identification sign indicating numbers of as many as one by one.Just as discussed below, the user can be to the different call treatment of different users' relevant CIN regulation.And different charging ways is relevant with CIN.Figure place by constituting those identification codes is as being respectively five and four users' that can be distinguished from each other PIN and CIN.
This interactive result, the business agent who is arranged in terminal 160 make the new user's of regulation the data record of distribution be stored in the memory of adjunct circuit 150 inside.An illustrative example having represented this record 300 among Fig. 2, a particular aspects of one of them or several fields specify personal telephone number business is as follows:
The HOME.PHONE(home phone number): the home phone number of stipulating the user.
SUB.PIN(user PIN): regulation is distributed to associated user's PIN, and can further stipulate relevant assisted user PIN.
The SUB.LANG(user language): the language-specific that identification is sent out public notice to this user.
The PHONE.NUM(telephone number): regulation is distributed to unique sequence call number of associated user, as 700-555-2234.
The quantity of NUM.MSG(message): regulation is stored in the quantity of the speech information in associated user's the information service system (not shown).
The quantity of NUM.CIN(CIN): regulation is distributed to the quantity of associated user's CIN.
CFNUM.1-3(calling transfer number): when by user program, stipulate each number for call forwarding.
The CALL.SEQ(calling sequence): the calling sequence of representing to implement the principle of the invention when setting is effective.
CIM1-4: stipulate each CIN and by this user-defined their each call treatment.
NU(need not): indicate no field or be not suitable for the present invention.
In case distributed intelligence has deposited record 300 in, after this this user can and upgrade this record with adjunct circuit 150 reciprocations: (a) call specific calling features, (b) change the value of the CIN of one or several distribution, (c) change each calling transfer number or (d) start calling sequence.
The user by dial his/she service number such as renewable this distribution of 0-700-555-2234 so that pass through the OSPS switch such as OSPS105 is established to the connection of the network 100 of adjunct circuit 150.The OSPS105 response receives through the calling of CO5, through communication path 106 adjunct circuit 150 is transferred in this calling.In exemplary embodiment of the present invention, path 106 for example can be a T1 carrier wave voice channel.OSPS105 also transmits relevant call information to adjunct circuit 150 through data path 107.Call information is particularly including (a) caller and called personal telephone number, (b) transmits the indication unique call distinct code relevant with this calling with (c) OSPS105 of the T1 channel of this calling.OSPS105 uses this call distinct code to call out relevant signaling information (message) through path 107 exchanges with this with adjunct circuit 150, as discussing below.Respond the reception and the related calling information of this calling, the called personal telephone number that adjunct circuit 150 will be received is translated into internal storage unit and from this memory cell dump data record 300 relevant with this telephone number.Adjunct circuit 150 prompting calling party (being the user in this example) input caller identification sign indicating numbers perhaps also do not provide under the situation of caller identification sign indicating number input pound mark (#) to caller this user then.In this example, the calling subscriber through relevant telephone set such as telephone set S1 set keyboard import his/her PIN of distribution.The PIN that adjunct circuit 150 responses are received compares PIN value of receiving and the PIN value that remains in the relevant user data record.In this example, adjunct circuit 150 finds that the former and the latter's value conforms to each other, so to the notice of a prerecording of calling subscriber's loopback, lists many calling features that this user can insert and/or upgrade.
An illustrative example of aforementioned calling features notice is as follows, and this notice is to provide with the language of stipulating in the SUB.LANG field:
" welcome to use your personal telephone number operation system.
Listen to your speech information and please press 1,
Programme or watch the calling transfer number please press 2,
Make a call home phone number or make a call to one and please press 3,
Want your caller identification sign indicating number of access please press 4, (1)
Start calling sequence and please press 5,
Stop this calling and please press asterisk pound mark (that is * #).”
This notice provides the superlative degree of the menu " tree " to the user can listen " menu ", and a numeral that responds this menu input digit 1 to 5 makes this system that further menu and the downward further submenu of this tree are provided, and can see from continue to narrate.
Suppose response warning tone (1) user by pressing the corresponding keyboard button input digit " 1 " of telephone set S1, then adjunct circuit 150 is to this response, the content of the NUM.MSG field of dump relative recording.If the content of that field equals zero, then adjunct circuit 150 sends this true message of expression to the calling subscriber.
If the value of NUM.MSG field contents is greater than zero, then adjunct circuit 150 loopbacks are enumerated the message of latter's field contents and the menu of the message that requires the access storage are provided.
By importing each keyboard digital, this user can be with accepting or refuse this requirement.
On the other hand, calling transfer number and therefore response notice (1) input digit " 2 " if the calling subscriber wants to programme, then adjunct circuit 150 is selected to respond with a menu notice in detail, and this user can select in conjunction with the calling transfer characteristic.An illustrative example of this menu notice is as follows:
" to watch the calling transfer number please press 1,
The calling transfer of programming number please press 2, (2)
Return main menu and please press asterisk pound record (that is * #) "
If this user responds notice (2), input digit " 1 ", then adjunct circuit 150 sends the oral form (verbal accounting) of CFNUM.1-3 field contents, and a menu is provided for this user, and wherein any of deletion or several chances are provided.
If this user's input digit " 2 ", his input of adjunct circuit 150 promptings reaches the calling transfer telephone number of (in this example) three 10; Specify a specific number that (or not having) is transferred to as calling wherein; With scheduled date and/or time, it is effective calling out any specific number of transferring to this calling transfer telephone number at this date and/or time durations.Adjunct circuit 150 is confirmed the input of each bar information by returning the notice that indicates this situation, and change is provided or ratifies its selection to the user.In case ratified, these data are deposited in the relevant son field (not shown) of CFNUM.1-3 field of relative recording.During any, the selection of the particular number that calling is transferred to friendship will surmount any calling sequence (being discussed below) that formerly starts during that.
After the user had withdrawed from the calling transfer characteristic by input " * # ", adjunct circuit 150 was retransmitted notice (1).Supposition now, the calling subscriber responds this notice input digit " 3 ", then adjunct circuit 150 send a prompting with determine this user whether wish to make a call one arrive his/her family or certain other place.
Suppose other place of calling subscriber's selective call, then adjunct circuit 150 asks the input calling subscriber to wish ten telephone numbers calling out to this response.When receiving this last numeral, it then sends a data message to OSPS105, and this data-message comprises call distinct code especially, is transferred to the request of the latter's telephone number by ten telephone numbers of user's input and this user's of request calling.At this moment, adjunct circuit 150 stops the control to this calling., this user wishes in the call home that the telephone number that then is stored in the HOME.PHONE field will be inserted in the aforesaid data-message if having shown.Under any situation, as discussing below, adjunct circuit 150 indication OSPS the expense meter of this calling to user's telephone service number.
The data-message that OSPS105 response is received also shifts this with the method for routine and calls out the telephone set of being discerned by the called phone number that is included in this message.For example, if the latter's telephone number and telephone set S4(Fig. 1) relevant, then DSPS105 transmits this through long-distance path 11 and calls out toll switchbroad 120.Switch 120 passes on through CO15 that this calls out telephone set S4 again.Therebetween, OSPS105 produce the station message recording with tracking time with to relevant call charge.
For the CIN of leading subscriber, this user also has and adjunct circuit 150 interactive abilities.In brief, the notice (1) that response is heard, this user calls this ability by input digit " 4 ".Adjunct circuit 150 provides menu and submenu thereof for this user to this response, lists many different selections in detail, relating to (a) increases, deletion renames and/or stipulates the call treatment consistent with each caller identification sign indicating number, and perhaps (b) watches these numbers.
Sometimes, this user may require to arrive any telephone number of different telephone number sequences, particularly, be that the calling of another number in those more preceding numbers is during by someone rather than this user answer even get in this sequence, arrive any number of those numbers.That is, this user does not have called place to connect this calling, and may connect this calling in the place relevant with a number of other telephone number.So and according to an aspect of the present invention, provide a mechanism, i.e. name is called out the previous telephone number in this sequence and is finished or " replied ", and this calling is sent in the telephone number in this sequence.The user can respond notice (1) and call this calling sequence mechanism by input digit " 5 ".Adjunct circuit 150 is to this response, send a prompting, the explanation that is transferred to the order that is stored in those telephone numbers among the field CFNUM.1-3 is called out in request input (a), (b) date and time that comes into force of calling sequence, comprise options: calling sequence comes into force till being cancelled by this user, and is perhaps as discussed above, after the starting calling sequence, start the one number calling transfer.Adjunct circuit 150 is by returning the notice that shows this situation and providing the option that changes or ratify them to confirm the input of various responses to the user.In case ratified, these data are stored in each son field of the CALL.SEQ field of relative recording.
After this, when a user rather than this predesignated subscriber were issued to this predesignated subscriber's the calling of service number, it was effective that adjunct circuit 150 is notified this caller's calling sequence.Adjunct circuit 150 also notify this caller he can be in proper order calling transfer number by this predesignated subscriber, as being described in detail below.But, through OSPS105 this call forward is arrived the telephone set relevant with first telephone number as long as at this moment say adjunct circuit 150, for example, being stored in first a specific telephone number that is designated as in the telephone number among the field CFNUM.1-3 in this order, is to illustrative the telephone number in field CFNUM.1.If if the line is busy or the people that replys this calling is not this user for called number, then the calling party for example can pass through then pound mark (#) request call order of asterisk (*).The OSPS105 response characterizes the reception of the signal of this request, is terminated to the connection of called phone machine, but remains to the connection of main dialing telephone.OSPS105 is connected to adjunct circuit 105 with main dialing telephone then.In addition, OSPS105 transmits a message through path 107, comprises especially: (a) caller and called number, (b) user's individual business telephone number, (c) call distinct code and (d) information of expression calling party request call order.At that time, adjunct circuit 150 obtains the next telephone number in this order, and illustrative ground is transmitted this then and called out OSPS105 for the telephone number in the CFNUM2 field that is included in relative recording.When doing like this, adjunct circuit 150 sends a message, comprises (a) calling number especially, (b) new calling sequence number, and (c) individual subscriber service telephone number and (d) call distinct code are as illustrated below.
Similarly, if the latter calls out that the line is busy or is replied by the people who is not this user, the method that can be narrated of caller request call order more then.In the sort of situation, adjunct circuit 150 is through the next telephone number of OSPS105 forwarded calls in this order, is to illustrative the telephone number that is stored in the CFNUM3 field of relative recording.Like this, according to the present invention, the caller can make adjunct circuit 150 orders by arriving this user by this user-defined each telephone number up to the caller.But if after the last number of these telephone numbers has been transferred in relevant calling, this caller still can not arrive this user, and then adjunct circuit 150 offers the selection that this called subscriber stays message for this caller.
Call treatment:
Referring to Fig. 1 and 3-8, suppose a caller, he can be the predesignated subscriber, dials this user's personal telephone number 700-555-2234.This is called out finally through network 100 switches, as the OSPS105 behind group prefix zero (" 0 "), and then extend to professional adjunct circuit 150 through a T1 channel in path 106, when receiving call setup message through data path 107, comprise the specific call identification code that (a) is called and calling number is relevant with this calling with (b) OSPS105 especially, (c) transmit the channel of this calling, as mentioned above, this receives adjunct circuit 150 program response, and returns a dialing signal and set up (square frame 501) as " dignified sound " desired connection of caller notification on relevant channel.
This program constitutes a message then, comprises the called number of receiving (as 700-555-2234) and makes this number effective request, and sends the message to a relevant database manager, is discussed below.Then the latter determine (square frame 502) user record whether assignment give called number.If like this, then database manager sends a message and gets back to the transaction processor, and this message shows that called number is effective.Otherwise this message shows that called number is invalid, and it makes this program send a notice on the channel of path 10b, shows that called number does not use (square frame 503).((call out termination messages and comprise relevant call distinct code to stop this calling to OSPS105 by square frame 504 by path 107 transmission calling termination messages for this program then.When receiving latter's message, OSPS105 stops this calling connection with the method for routine.
If called number is effectively, then this program line sends " welcome " notice (square frame a 506) request input PIN of prerecording by relevant channel.Be an example of this notice below.
" welcome to use individual's calling system.
If you are from push-button telephone dialing and have people one by one to call out identification, please import it now, then an input pound record.As long as otherwise press a pound mark ".（4）
Identification (ID) sign indicating number on these sequential monitoring path 106 channels then, i.e. PIN, one of CIN or both, and the reception of # symbol.For example,, do not receive ID sign indicating number or # symbol (square frame 507), then send one and re-enter message (square frame 509) if when finish 10 seconds.If at this moment ID sign indicating number or # symbol are not all received (square frame 510), then this program sends a message, shows that this calling will stop (square frame 512), and the method for stating of chatting face to face more than then stops this calling (square frame 504).
On the other hand, if this program is found calling party's (square frame 507 or 510) of response " welcomes " notice, whether what then it detected that (square frame 508) look at that this side imports only is # symbol.If situation now, then program advances into square frame 523(Fig. 5).On the other hand, if the calling party has imported the ID sign indicating number, then this program is by sending a validity of checking (square frame 519) input (PIN or CIN) to aforesaid data base querying.
If the message of returning from database shows that this input is invalid, then this programmed check sees that whether it is to present calling and setting retry sign (square frame 520).Be set as sign, mean that this is the input second time of invalid ID, then this program enters through square frame 512 and 504 and stops this calling.If the retry sign is not set, then its (square frame 521) of this program setting asks to import a 1D or # symbol (square frame 509) then again.
If it is that effectively then this program is worked with database that database message shows this input, transmit any speech information that (square frame 513) may be stored in this database to the caller.The identification code (square frame 522) of this programmed check input determines if it is a PIN then, promptly comprises five digit number.If not, then this programmed check sees whether (Fig. 5 square frame 523) calling sequence is effective.If invalid, then this program (square frame 524) determines whether this calling should transfer to this user's home number, and if find it is this situation, the dump latter's number (square frame 525) from relevant user record then.Program (square frame 526) constitutes a calling transfer (CF) message then, comprise (a) called number especially, (b) calling number, (c) called telephone number and (d) OSPS105 call distinct code relevant with incoming call, this program determines whether this caller imports a CIN(square frame 528 then), if this is the case, in CF message, import a specific accounting code (square frame 529) to show what this calling will be paid by the called subscriber.Otherwise different accounting code of this program (square frame 530) input is to show that this calling is by caller-pays system.This program sends this message (square frame 531) to OSPS105 on data path then, and original call information receives from this data path such as path 107.This program withdraws from then.
If this program (square frame 524) finds that this calling is not to transfer to user's home phone number, the telephone number (square frame 532) stored in the CFNUM.1 field of associated user record of its dump then, the method for stating of chatting face to face more than then continues (promptly continuing to carry out square frame 526).Must be pointed out that in this example this calling is transferred to the first calling transfer number, if but the line is busy or can not utilize this user of called place for this called number, and then after this this calling will not transfer to the second calling transfer number.Its reason is that calling sequence is not effective.But, be effectively if the CALL.SEQ field of associated user's record is represented calling sequence, then aforesaid, program sends (square frame 535) and shows that this calling sequence is an effective notice on the channel that transmits calling.Program (square frame 525) offers the exemplary example of caller's notice can be as follows:
" this is personalized call business.
The side that you have called out has stipulated to receive this side's telephonedirectory.These telephone numbers can sequentially be attempted.For the calling that makes you proceeds to next number in this table, please press " asterisk pound mark " at any time even this calling is replied, if specific telephone number is not replied, even " asterisk pound mark " be not input also, after 5 rings, also will automatically attempt next number, attempt first number now ".
But before transmitting this notice, the telephone number of storing in the CFNUM.1 field of this programmed dump (square frame 533) relative recording as the telephone number of telephone set S4, forms a calling sequence (CS) message (square frame 534) then.(except this type of message is to point to the calling sequence, the content class of CS message is similar to the content of CF message).
Whether program (square frame 528) check caller has imported relevant identification code, i.e. a CIN then.If this is the case, then program to insert a designator (square frame 529) so that notify this calling in this message be to the charge of user's personal telephone number.Otherwise it is to caller's charge (square frame 530) that the designator of insertion is notified this calling.Program sends (square frame 531) this message to OSPS105 through path 107 then, withdraws from then.
The reception of response adjunct circuit 150 message, OSPS program (square frame 600 of Fig. 6) the content stores of this message in the call record relevant with this calling (square frame 601).Program makes OSPS105 shift this and calls out the destination of being discerned by the calling transfer number that is included in this message (square frame 602) then.If not indicate calling sequence be (square frame 603 and the 603-1) that comes into force to the message of Jie Shouing then, the control that this program will be called out is sent to conventional call processing program.Otherwise this program begins to monitor that the calling of receiving * # signal connects, shows caller's incoming call order request (square frame 604).During this supervision, a good chance is arranged, promptly not that this user's someone can reply this calling in called destination, and after talking, stop this calling by on-hook with the calling party.If this occurs, the CO of service called phone machine will should the fact with the method notice destination toll switchbroad such as the TS120 of routine.Then, the latter's toll switchbroad sends a clear message to OS-PS105.Therefore, during this monitored, this program (square frame 604-1) check was from the reception of the next clear message of destination toll switchbroad, if it receives this message, the transfer that just is disconnected to the destination switch connects (square frame 604-2).Otherwise, the request whether this program (square frame 605) check receives calling sequence.If it does not receive this request, then whether program (square frame 607) check calling party has stopped this calling, then continue to monitor this calling (square frame 604) if not this situation, but, if this program finds that the calling party has stopped this calling, if this calling is finished, then program is finished the conventional station message recording (square frame 608) of a people.This program is stored this record in billing database then, and the content of billing database will later handled by the charging center, so that each call is chargeed.This program (square frame 609) stops this calling then, withdraws from subsequently.
Suppose that the caller imports the request of a calling sequence, if perhaps called phone number ring 5 times and also not replying, then (calling transfer that the square frame 610 of Fig. 7 is disconnected to the destination toll switchbroad connects (if it before was not disconnected (square frame 604-2)) to the OSPS program, then from the relevant call record (square frame 611) of memory dump.If this calling is finished, then this program is set (square frame 612 and 614) one " software mark " to predetermined value.Otherwise this program reset should sign (square frame 612 and 613).Whether this program produces a station message recording (square frame 615) then, and finish according to the relevant calling of value notice of aforementioned sign.Aforesaid then, this program is this station message recording of storage in relevant database.This program forms a CS message (square frame 617) and provides this message to adjunct circuit 150(square frame 618 through relevant data path such as path 107 then).Final program withdraws from.
When receiving the CS request message, (send) at the square frame 618 of Fig. 7 from OSPS105, adjunct circuit 150 programs obtain be included in CS message in the duplication (Fig. 8 square frame 701) of the relevant user record of business telephone number.This program compares with telephone number among the CFNUM.1-3 that is included in the relative recording field with the called number that the order of being determined by predefined procedure will be included in this message then, up to it find conform to till.If conform to the final number of this order, this means that all numbers have all attempted, promptly this order has been used up.(square frame 702), this program transmit a notice (square frame 704) by the channel of discerning and are provided as the selection that the called service user stays speech information to the caller in CF message if this is the case.If the calling party accepts this selection (square frame 705) by suitable keyboard (MF) character such as the pound mark (#) of input, then this program forms a message, comprise the telephone number of called subscriber's speech information business especially and shift the request that this calls out the telephone number of identification, and send the message to OSPS105(square frame 706).OSPS105 disconnects from the calling of adjunct circuit 150 then and shifts this and call out called destination.This program withdraws from then.If this user does not accept this selection, then this program stops this connection (square frame 707) by sending a clear message to OSPS105.
If the number that conforms to is not the final number in this order, then this program will comprise the CF call setup message transmission (square frame 703) of the next number in this order to OSPS-105(square frame 708).This program withdraws from then, thereby stops to the control of the calling of OSPS105.OSPS105 shifts relevant calling then to the destination of being discerned by the latter's number, narrates as top.
If this program (square frame 522 of Fig. 4) is found to comprise five digit number by the number of caller's input, then this program concludes that the calling party is this user, and transmits (square frame 527) notice (1) to this user through path 106T1 channel.This program is waited for user's selection (input) then.When receiving this input, this program proceeds to a suitable subprogram (square frame 532-1,532-2,532-3,532-4 or 532-5) is handled this user with method discussed above selection.
A possible preferred embodiment of adjunct circuit 150 is shown among Fig. 9.Specifically be that adjunct circuit 150 is connected to the switch 105 of a plurality of networks 100.In an illustrative alternate embodiments of adjunct circuit 150, each such switch 105 can be can be from AT﹠amp; The known No.5ESS switch that T company has bought.For improving its reliability, adjunct circuit 150 comprises two parts, and wherein the parts in such part are duplications in another such part.Therefore, the discussion of Yi Bufen adjunct circuit is equally applicable in another part.
Particularly, each such part comprises one group of transaction processor 10(11), each processor 10(11) be connected to separately interchanger 105 through relevant communication path 106.As mentioned above, communication path 106 for example can be so-called T1 carrier line.As everyone knows, the T1 carrier line provides many channels to be used to transmit each call.Each such part also comprises X.25 a front-end processor (FEP) 50, SNA processor 55, LAN15 and a computer 60 relevant with magnetic disc store 66.X.25FEP50 realize known X.25 Data Transport Protocol, and be the device of the relevant portion of adjunct circuit 150 by it and an OSPS switched call signaling information.That is, arrange X.25FEP50 so that the call signaling information that it provides this FEP50 to receive from separately switch 105 through LAN15 to its relevant computer 60.Similarly, the call signaling information that X.25FEP50 provides FEP50 to receive from relevant computer 60 through LAN15 to separately switch 105.In this respect, X.25FEP50 be connected to each switch 105, each switch be connected to relevant portion transaction processor 10, X.25FEP50 and the connection between these switches 105 with path 107 expression in the figure.
Calling and outgoing call and relevant call information and the processing that is stored in the data base administration of the user record in the magnetic disc store 66 are to be handled by relevant computer 60, and for example it can be the VAX-9000 of Digital Equipment Corporation.In this respect, computer 60 is centers of adjunct circuit 150, and transaction processor 10(11) with X.25FEP50 be used for computer that they are relevant 60 and switch 105 interfaces.In addition, as the further method of improving the redundancy of adjunct circuit 150, each computer 60 is connected to the LAN15, as shown in the figure.
As above-mentioned, new user record is by terminal 160 inputs that have the people to operate.Terminal 160 is connected to every part of adjunct circuit 150 through each SNA processor 50.Each SNA processor 50 is implemented known IBM SNA agreement, and is used for terminal 160 and each computer 60 interfaces.Therefore, the user record of new input is sent to this two computers 60 through their each SNA processor 50 and LAN15.These two computers 60 are the new record of storage in their magnetic disc stores separately again, perhaps to the change of existing record.Computer 60 also can receive new user record from another adjunct circuit 150 through relevant Data Bridge device 45, perhaps to the change of existing record.Like this, as above mentioned, each adjunct circuit 150 is keeping the renewal duplication of each user record.
Referring now to Figure 10,, expression comprises the roughly branch block diagram of the OSPS105 of call processing device 430 and switch architecture 405.More particularly, the repertoire that call processing device 430 controls are carried out by OSPS105, and according to the indication execution that is stored in the call processing device program in the calling memory 435.These functions comprise conventional phone operator service and with said method and adjunct circuit 150 interfaces.More particularly, this interface comprises communication path 106-1 to 106-N and front-end processor (FEP) 410.Particularly, the call that receives through a paths 104 that extends to one or several CO is provided for switch architecture 405.This is responded, and switch architecture provides relevant call information to call processing device 430 through bus 425.Aforesaid, this call information can comprise a called number relevant with adjunct circuit 150.If situation is such, that is, called number comprises one 700 prefix, and then processor 430 indication switches 405 send this through one of communication path 106-1 to 106-M and call out adjunct circuit 150.When doing like this, processor 430 provides relevant call information and aforesaid call indicator to arrive FEP410 through bus 425, and is so that be sent to adjunct circuit 150 through data path 107, as described above.Also as described above, OSPS, promptly processor 430 will call out be stored in memory 440 in call record be associated.Another kind of scheme, FEP410 will offer call processing device 430 through bus 425 through message such as the CS message that path 107 receives.Then processor 430 according to narrate above and be stored in this message of routine processes in the calling memory 435.
More particularly, the CS message that calling is connected to the calling party will monitor that processor 430 makes one of switch 405 bridge joint MF receiver 415-1 to 415-P to this connection to the input of calling sequence request.Like this, as discussed above, this connection monitors the input of this request.When the receiver that connects detected the signal that has this request of sign, then it was through bus 425 notification processors 430 these situations.When processor 430 be sure of that this request is rational, then it notified this fact through FEP410.In addition, processor 430 change connected be configured to disconnect the callee, if desired like this, and connect caller to adjunct circuit 150, as described above.
If aforementioned messages is to call out connection message from the routine that the destination of an identification is transferred in this calling, then processor 430 indication switches 405 disconnect from the path 106 calling.Processor 430 indication switches 405 are set up incoming call and are connected and this be connected of a long-distance suitable network path 111 then, and this calls out the route of its intended destination as transfer.When doing like this, processor sends the so-called CCS message of this calling of identification to this destination through CCS network interface 450 and CCS network 250.
On the other hand, processor 430 sends the incoming call of not attached prefix 700 to one of a plurality of phone operators through interface or trunk line 420.With operator's position 455 expressions, operator's position is handled these incoming calls with conventional method to these operators in the figure.
The narration of front just illustrates principle of the present invention.Therefore know that those skilled in the art can design that a lot of devices are implemented principle of the present invention and be in their spirit and scope, though these devices are not clearly represented and narrated here.For example, can understand that when the calling sequence characteristic was effective, adjunct circuit 150 can easily be suitable for so that it at first sends the phone of calling out this user's family, sends this in proper order with this then and calls out each telephone number.In addition, very clear though the present invention imports specific keyboard signal request call order with the caller, the identification equipment that OSPS can adopt so-called and speaker-independent says that with the permission through port it imports this request.This equipment obtains easily and adopts word fixed point (word-spotting) algorithm, and this algorithm is applicable to fixed point " calling " and " in proper order " these words.In addition, that narrates previously can be used easily, make it (a) from the request of caller or callee's call accepted order, (b) only the calling of replying is at last produced a station message recording in this order, send to one of relevant calling transfer number, perhaps (c) automatically send in order call to each calling transfer telephone number so that do not need the square incoming call order request of caller (or called), even replied at one of calling transfer telephone number.In addition, that narrates previously can easily be used, so that if calling sequence is effective and caller's on-hook before all calling transfer telephone numbers are all attempted, but redial user's individual service number in during preset time, then provide the selection that continues calling sequence, do not have on-hook as the caller to the caller.Another kind of scheme, if calling sequence also is effective and caller's on-hook before all calling transfer numbers are all attempted, this system can be immediately to caller's phone ringing, when that telephone answering, the notification call person has other NA number in this table, unless the caller is on-hook at this moment, also to notify the next number that to attempt in this table.
Though choice menus is regarded the calling transfer (selection of main menu " 2 ") and the calling sequence (selecting " 5 ") of individual call as separately management function in this illustrative embodiment, but they can be combined into single call forwarding function, are to single telephone number or to an order by this user-defined transfer wherein.In addition, this system can be arranged to allow this user to stipulate a plurality of calling transfer orders, when asking by discerning with identification code, can make one of them specific sequence effective when user's request.
In this illustrative embodiment, only when this calling beginning, provide a calling sequence notice and instruction to the caller.But in other embodiments, these notices and instruction can provide at each appropriate time of this calling, when terminating in any calling of having replied in this order the callee.
